Abstract The invention relates to a method for determining the speed of vehicles (1) on a roadway (2), in which a first measuring system and a second measuring system are provided, the first measuring system is provided with a sensor device (5) covering a detection area (7) and a first time measuring device (8), wherein the first measuring system measures at several points of time the distance (D) of a vehicle (1) moving within the detection area (7) and determines by means of the distance (D), changing over time, a driving speed (vpe) of the vehicle (1) and the second measuring system checks the determined driving speed (vpe), characterised in that the second measuring system is provided with a second time measuring device (9) being independent of the first time measuring device (8), wherein the second measuring system monitors by means of the sensor device (5) a virtual entry line (11) of a roadway section (10) situated within the detection area (7) and records by means of the second time measuring device (9) an entry point of time (ti), at which the sensor device (5) detects an object point at the entry line (11), wherein the second measuring system checks at least at a later check point of time (t2 ) by means of the sensor device (5), whether an object point is within a defined section window (2xi) around a virtual exit line (12) of the roadway section (10).
